I need to get an alingnment done on my 79way cherokee. This is the second one in less than 3 months. The quy at the shop i took it to said there is only one adjustment to be made. Then the other day my buddy was behind me and told me it looked like i was driving sideways. Is the guy atthe shop i took it to full of it or just doesn't know what he is talking about. How many adjustments should be getting made?

There is only one thing that's really adjustable with a solid front axle and that's toe (tow is what you do when you pull something behind your vehicle). Camber and caster are not an adjustable measurement without special parts and the adjustment you can do is pretty limited. Any shop, regardless of what they can or can't adjust, can give you a printout of what the measurements of camber, caster, and toe are along with what they are supposed to be. At least then you would know if something is out of whack.

No self-respecting shop is going to adjust caster with shims between the springs and perches. Shims are hack and are a liablility to a shop should they break. They will use an adjustable spanner on the top balljoint, but you can only get a couple of degrees of alignment out of them at most.

Keep in mind that the front axle on a fullsize Jeep is wider than the rear axle, so looking down one side it can look like it's doglegging.

You don't adjust pinion to correct caster. Yes, I know that one affects the other, but caster always takes priority and there isn't a specification for pinion angle. There is one for caster. I know this may sound nitpicky, but I don't want someone to think that they can move their pinion to an angle they think is correct and assume that caster will be correct too based on your statement that if you adjust pinion, caster should be correct.

Another possibility could be the centering pin on a rear leaf spring pack is broken causing the axle to not be positioned correctly on the spring. Because of this the thrust angle would be off. Just throwing that out there

So I was checking out my rear leafs today and the long bolt coming out of the center of the passanger side leaf is pretty bent could that be the cause of my problems? How hard is it to replace?
